fix(mix): set `emqx_vsn` compile info 

Currently, `emqx_release.erl` depends on the `erl_opts` option
`compile_info` being set by Rebar3 to include `{emqx_vsn, $PKG_VSN}`
to report the version, for instance, in `emqx ctl status`.

Since Mix does not provide a simple way to pass `erl_opts` to Rebar3
dependencies without creating a `mix.exs` file, the workaround is to
set the environment variable `ERL_COMPILER_OPTIONS` to include that
value before invoking the Erlang compiler on the Rebar3 dependencies.
